After a supernova, the stellar core may remain as a neutron star or, for more massive stars, collapse into a black hole. Neutron stars are extremely dense, composed almost entirely of neutrons, while black holes have such strong gravity that not even light can escape from them.

How much does a supernova weigh?
A supernova itself doesn't have a specific weight as it is not a single object but rather a stellar explosion marking the end of a star's life cycle. The mass involved in a supernova can vary widely, often between 1.4 to several tens of solar masses (the mass of our Sun). During the explosion, a significant portion of the star's mass is ejected into space, while the remnant core may collapse into a neutron star or black hole.
In the last stage of stellar evolution following a supernova stars too massive to form neutron stars may form a?
In the last stage of stellar evolution, stars too massive to form neutron stars may collapse into black holes following a supernova explosion. When these massive stars exhaust their nuclear fuel, their cores collapse under gravity, leading to an event horizon that characterizes a black hole. The outer layers are expelled during the supernova, while the core's collapse results in an incredibly dense singularity from which nothing, not even light, can escape. This process marks the end of the star's life cycle, transitioning it into a black hole.
A what is produced when the outer core of a star explodes after the core collapses?
The process of the stellar explosion is called a "nova", or if powerful enough, a "supernova". The outer layers of gas are blown away into space, and this shell of fleeing gas is sometimes called a "supernova remnant", or more generally, a "nebula". For example, the Crab Nebula is the gas cloud left over after a supernova explosion which was brilliantly visible here on Earth in the year 1054.
What determines which stage occures after a supernova?
No one knows for sure, since there is not enough information to figure it out. After a supernova, the star will either turn into a black hole, a neutron star, or a pulsar. But, there is no scientific evidence that proves which one the star will turn into after a supernova.
Which element in the core of a high mass star leads ultimately to a supernova explosion?
The Answer may be hydrogen. Hydrogen moves to the suns core as it starts to die, or explode. hydrogen is a very flammable gas. A star, like the sun is surrounded by heat. this heat will ignite the hydrogen gases as it moves to the core. This ignition of the hydrogen will cause the star to expand in size and increase in temperature.

Are there planets orbiting suppernovas?
No. A supernova is star that is exploding. If any planets are orbiting a star that explodes, they will be destroyed. There is evidence that after a supernova new planets may form from the debris cloud left behind and orbit the stellar remnant, which will be either a neutron star or a black hole depending on the mass of the star that exploded..

What type of stars hotter?
The hottest stars are supernova explosions, which may reach temperatures around a billion kelvin in the star's core.
What happens to a massive star when its fusion period is over?
Once a star's nuclear fusion has ended, it will collapse inside its core and become what is known as a white dwarf. Its outer layers will shoot out into the universe as planet nebula. If they are very large, stars will explode into a Supernova and their core will collapse into a black hole.
When does a type 2 supernova begin to explode?
A massive red supergiant star will eventually explode as Type II supernova. That happens when the high mass star has run out of its nuclear "fuel". A series of nuclear fusion reactions finally ends at the nucleus of iron. A massive core of iron remains and iron can't be used to produce energy by nuclear fusion. The core collapses under gravity and the energy released throws the outer layers of the star into space in a supernova explosion. This is a Type II supernova. Sometimes it's referred to as a "core collapse" supernova, for obvious reasons. A bit more detail, if needed: A "high mass star" in this context is one with a mass of at least 8 times the mass the Sun. They develop into red supergiant stars. The mass of the iron core needs to be over the "Chandrasekhar mass" of about 1.4 times the Sun's mass. A core of that mass is unable to resist gravitational collapse. Depending on the mass of the iron core, collapse may stop at a "neutron star". Otherwise there is a complete collapse to a "black hole". See "Sources and related links", below.
A star the size of two stellar masses forms as a result of a supernova explosion what is the star called?
Following certain types of Supernova events there can often be a gravitational collapse of massive stars and this can result in the stellar remnant becoming a neutron star. Based on the Tolman-Oppenheimer-Volkoff limit the solar mass of a neutron star can range from 1.5 to 3.0 solar masses.
What determines which stage occurs after a super nova?
No one knows for sure, since there is not enough information to figure it out. After a supernova, the star will either turn into a black hole, a neutron star, or a pulsar. But, there is no scientific evidence that proves which one the star will turn into after a supernova.
For supernova explosions caused by collasping cores the core itself will either become a neutron star b white dwarf c black?
In a supernova explosion, the core of the star typically, we believe (because we've never had an actual example to study) collapse into a black hole. There may be some cases in which the core is "only" compressed to neutron-star density, but our understanding of the mathematics of extreme gravity and pressure is a little weak around the edges there.
Does a supernova implode or explode to form a black hole?
It depends on the mass of the star. When massive stars die the result is usually an enormous explosion called a supernova, but the core will collapse to form a dense remnant. If the remnant is less than 3 times the mass of the sun then it will form a neutron star. If it is greater than 3 times the mass of the sun it will form a black hole. Extremely massive stars may collapse directly into a black hole with no supernova.
